Nervous system diseases вЂ“ sleep disruption and hallucinations can be symptoms of behavior and mood disorders.Sleep disorders вЂ“ hypnagogic hallucinations are key symptoms of narcolepsy.Substances, including cannabis and alcohol.Risk factors linked to hypnagogic hallucinations are: For example, during both REM and hypnagogic hallucinations вЂ“ an area of the brain called the thalamus is more strongly activated, and there is an increase of the chemical messenger acetylcholine. In support of this theory, researchВ has shown there is similar brain activity between REM and hypnagogic hallucinations. Many scientists believe that hypnagogic hallucinations can be caused by REM sleep intruding into wakefulness. Research has shown there is similar brain activity between REM sleep and hypnagogic hallucinations. The sleep stage associated with dreaming is called rapid eye movement (REM) sleep.

However, itвЂ™s likely that REM sleep plays an important role.Дuring sleep, the brain moves through a series of different stages. Hypnagogic hallucinations may happen for a variety of different reasons. What Causes Hypnagogic Hallucinations? Biology of Hypnagogic Hallucinations A sample study from the USВ showed 25% of participants experienced hypnagogic hallucinations, and these hallucinations were more common in women and younger age groups. In the UK, an estimated third of the population experience hypnagogic hallucinations. Scientific data suggests that hypnagogic hallucinations are relatively common. Hypnagogic hallucinations may appear spontaneously with no apparent cause. As such, they can be more disturbing for people. Hallucinations in a hypnagogic state may seem more real than hallucinations in dreams. These hallucinations are separate from the types of hallucinations that happen in dreams. Hallucinations sometimes appear in hypnagogic and hypnopompic states. Gustatory: having a taste in the mouth that has no physical source.Olfactory: smelling things that have no physical origin.

Tactile/physical: feeling physical sensations on the body surface when nothing is stimulating the skin or feeling motion in the body when it is still.

Auditory hallucinations: hearing voices and sounds that have no physical origin.

Visual hallucinations: seeing things, such as people, colors, and shapes, that arenвЂ™t present.

Hallucinations are defined as sensory experiences that happen in absence of stimulation by the relevant sensory organs. The term hypnopompicВ was coined soon afterward and describes the onset of wakefulness. Consisting of the Greek words вЂњhypnoвЂќ, meaning to sleep, and вЂњagogosвЂќ meaning induced, the hypnagogic state describes the state of consciousness during the onset of sleep. The term hypnagogic was coined by the French physician Alfred Maury in 1848. WeвЂ™ve discussed some of the symptoms, causes, and mechanisms of hypnagogic hallucinations so you can better understand why and how they might occur. Similar to lucid dreaming and sleep paralysis, scientific researchers think that hypnagogic hallucinations are related to REM sleep, the stage of sleep most associated with dreaming. Sometimes people may see, hear and feel things that donвЂ™t exist during the hypnagogia phase вЂ“ these are called hypnagogic hallucinations. Hypnagogia is the transition period between wakefulness and sleep.
